To all whom it may concern:

Be it known that BLooMrmLn H. HowAnn and ERNEST J. TURNER, citizens of the United States, residin res actively, at Washington, District of olumhia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to rovide a feeder for ingot molds adapted to he supported on the u per end of the mold and also provide a fee er which will prevent the formation of what is known as piping and at the same time reduce segregation.

Another objectof our inventlon is to provide a feeder havin a large number of curved walls adapted to correspond with the walls of the mold whereby any imperfections in the wall of the ingot is more readily rolled out during the rolling rocess and which also enables the scale on t e outer pe- IIFhQIX of the ingot tomore readily peel off 0 the ingot during the rolling process, and thus produce a more perfect finished article. A further object of our invention is to provide a feeder of this character which can be readily and cheaply made by dies and a supporting means formed as an integral part thereof and serving as means for strengthening that portion of the feeder above the mold and is an improvement over Figure 1 of Patent No. 1,481,205 dated January 15, 1924, which figure was incidentally shown but for which no claim was made. In the accompanying drawings Figure 1 is a perspective view of an ingot mold showing our improved feeder applied thereto. Figure 2 is a vertical transverse sectional view of Figure 1.

Figure 3 is an enlarged top plan view partly broken away.

Figure 4 is a top plan view of a modified form of feeder.

Figure 5 is' a vertical transverse sectional view of Figure 4. v

Figure 6 is a top plan view of a still further modified form of feeder, showing the supporting ribs arranged so that the feeder can be reversed in the mold.

. Figure 7 is a vertical transverse sectional view of Figure 6. r

walls bellied inwardly as indicated at 3, 4, 5.

and 6 which are oppositely arranged and connected by the four short corner walls 7, 8, 9 and 10 which as shown in Figure 3 are of a modified form. Carried by the outer periph= cry of the feeder are the vertically disposed semi-circular supporting ribs 11 which terminate a considerable distance from the lower end of the feeder to allow a portion.

thereof to enter the feeder as clearly shown in Figure 2 of the drawings. We have shown the outer faces of the walls 3,4, 5 and 6 concave. This is done so thev outer walls of the feeder will conform to the inner walls of the mold and will save material in the manufacture of the feeder. It will also be understood that the inner walls of the feeder could be straight or of any other contour without departing from our invention.

- In Figures 4 and 5 we have shown a rectangular feeder having the four bellied walls 12, 13, 14 and-1'5 oppositely arranged and connected by the four straight walls 16, 17,- .18 and 19. In this form the. supporting.

ribs 20 are arranged on the outer periphery in the same "relative position as that shown in Figures 1, 2- and 3 for supporting the feeder on the mold with a portion thereof extending into the mold asshown inFigure 5.

In Figure 6' we have shown a mold having the four bellied waiis 21, 2:2, 23 and 24 opre 8 showing straight interior walls with sllght-ly four inwardly curve positely arranged. The bellied walls 22 and 24 have ends terminating in the curved walls 25, 26, 27 and 28 and connecting these curved walls 25, 26, 27 and 28 with the walls 21 and 23 are 'the straight walls 29, 30, 31 and 32. In this form shown in Figure 6 the supporting ribs 33 are arranged intermediate the ends of the feeder and nearer one end than the other so that the feeder can be reversed E to allow the feeder to extend a greater or less distance into'the bore of the mold. The upper and lower edges of the-feeder are beveled as indicated at 34 and 35.

In the modification shown in Figure 8 the four walls 37, 38, 39 and 40 are bellied to a reater extent than that shown in the other gures and are connected by walls 41, 42, 43 and 44 oppositely arranged. In this form a supporting rib 45 is shown carried by the outer face of each of the belfitsad walls and also each of the straight wa In Figured 9, 10, 11 and 12 as heretofore stated we have shown the forms of feeder shown in Fi interior wa s are straight with slightly rounded corners in which like reference numerals indicate like Having thus fully escribed our invention arts.

what we claim is 1. A feeder for in 0t molds comprising walls connected by four walls of a different contour.

2. A feeder for ingot molds comprising a bod portion havin inwardly bellied, opposite y arranged wa s, connected by shorter oppositely arranged walls and supportin ribs carried by the outer face of said wa 3. A feeder for ingot. molds comprising a body portion having inwardly belhed walls carried the straight res 1, 4, 6 and 8 in which the oppositel arm and. su rting means y the outer fac f the body portion.

4. A feeder for ingot molds com rising a body posite y arranged walls connected by inwardly curved walls.

5. A feeder for ingot molds comprising a body portion havin inwardly bellied, oppositely arran ed wa ls and supporting llbs carried by t eouter periphery of the body portion.

6. A feeder for ingot molds comprising a body portion having four oppositely arranged, inwardly bellied walls connected by four oppositely arranged short walls.

7. A feeder for ingot molds comprising a body portion .having four inwardl bellied oppositely arranged walls connecte by four oppositely arranged walls of a differentv contour.

8. A feeder for ingot molds comprisiig four inwardly bellied oppositely arrang walls connected by oppositely arranged ortion havmg inwardly'be 'ed, op-

walls of difl'erent contours and supporting ribs semi-circular in cross section carried by the outer face of the wall.

9. A feeder .for ingot molds comprising a body portion having inwardly belhed outer faces and straight inner faces.-

10. A feeder for ingot molds compgsigg a body portion having inwardly lli outer faces oppositely arra and connected by shorter outer belhed faces and straight inner faces slightly rounded at the corners.

In testimony whereof we aflix our signatures BLOOMFIELD H. HOWARD. ERNESTJ. TURNER.
